Karnaugh maps for 2 to 5 variables in Gray order, grouping rules, prime and essential prime implicants, don't-cares, minimal SOP and POS, and the Quine-McCluskey tabular method with the prime-implicant chart, row and column reduction and Petrick's method for cyclic charts.
Map layouts for 3 and 4 variables in Gray order with cell numbers, adjacency and wrap-around, group size and literal count, prime, essential prime and redundant implicants, the grouping routine with don't-cares, a fully worked 4-variable map with two minimum covers, the minimal POS from the zeros, a 3-variable and a 5-variable example, and the usual counting traps. All implicant lists come from a Quine-McCluskey script.

The Quine-McCluskey method step by step: grouping minterms by the number of 1s, merging terms that differ in one bit with aligned dashes, checking off merged terms, reading prime implicants, the prime-implicant chart with essential columns, row and column dominance, Petrick's method for cyclic charts, and how don't-cares enter. A full 4-variable tabulation and chart and a cyclic 3-variable chart, all generated by script.
